The problem with this approach is that you only secure the address and not the rest of the packet, so you end up with two crypto functions to execute.
Also there are other contenders for the suffix such as the arrival action as per network programming, and the perhaps per hop action as per foam. Now I suppose that this simply means a much longer address and the semantics of the stuff that follows the prefix is defined by the address, but then I think that it is better to simply call that a blob defined by the prefix rather with no formal semantics in the protocol and leave the definition of the blob to the network application designers. There is clearly quite a lot to study in terms of multi-semantics which I think really should be taken out and put in its own draft. - Stewart > On 8 Feb 2021, at 10:05, Jiayihao <[email protected]> wrote: > > As for address embedding public key, it need not to carry any algorithm in > the address.
